Chest-blocks are versatile techniques that can be effective counter-attacks. This drill explores ways to use the outside chest block followed by an inside chest block as a defensive response to a wild punch or sucker punch. Key combative principles here are using the larger surface area of the forearms to help guarantee effective striking (it’s easier to hit your target while full of adrenaline if you use a larger striking surface), getting off the centerline of your enemy while keeping him on your centerline, and using body dynamics to generate power in the strikes. I call this technique Hulk smash. The video demonstrates the partner drill as well as an accompanying pad drill.
